It is official. 2020 was the joint hottest year on record for Planet Earth 📈

This was the hottest year on record for Europe.

Data @CopernicusEU

[THREAD]

Official report from @CopernicusEU ⬇️

climate.copernicus.eu/copernicus-202…
So 2020 was ties hottest with 2016?

This is what 2016 looked like. Exceptional Arctic warmth like 2020 but slightly different places to 2020.

There is an important difference between 2016 and 2020 though.
A global glance at 2016 beside 2020 reveals something striking about the Pacific.

We had El Niño in 2016. 2020 developed La Niña.

2016 left, 2020 right.
I have already made a thread zooming in on parts of the world using 2020 data.

Still waiting on other bodies to make statements on 2020 ranking.
Regardless of rank. 2020 rivalled the global heat of 2016 without the boost of El Niño warming in the Pacific.

This is probably one of the biggest takeaways here.
Finally...

I have summarised all these graphics on my website along with other animations.

Hottest year on record for Europe?

The following countries so far have confirmed 2020 as:

Hottest year on record: 🇳🇴🇸🇪🇫🇮🇪🇪🇱🇻🇨🇭🇫🇷🇳🇱🇧🇪

2nd hottest: 🇵🇱🇩🇰🇩🇪
3rd hottest: 🇬🇧
5th hottest: 🇦🇹

Map data using @CopernicusEU ERA5 reanalysis. Comparing temperature to 1981-2010 average.
USA 🇺🇸 preliminary data suggests they had 5th hottest year on record. Strongest heat in the west. Note USA recorded a new world record for reliable hottest world temperature, 54.4 °C (129.9 °F) on 16 August.

Awaiting official verification from neighbouring countries.
Parts of Canada were among few places in the world which showed slightly cooler than normal for 2020. Not that warm in parts of Alaska either.

Earth has a fever in more ways than one. Some places averaged + 5-7 °C warmer than normal for the ENTIRE YEAR of 2020.

An enormous area of anomalous warmth plagued Arctic Siberia effectively all year but it was not just the Arctic where we saw record shattering warmth.

THREAD
Another way of looking at it... Very few cold blobs left. La Niña developed and shows up in the Pacific.

The climate is not changing uniformly, the Arctic is warming much faster than the rest of the world.

Data: @CopernicusEU and compares to 1981-2010 average.
JANUARY was joint hottest January globally on record according to NASA GISTEMP v4 (joint record with 2016).

Profound winter warmth for North America plus Europe and Asia.

Parts of the Arctic averaged up to +14 °C above normal for the entire month of November.

Preliminary data suggesting we witnessed the hottest November globally on record.

2020 is on track to be the hottest year on record.

[THREAD]
Cold in Canada,
Cool La Niña in the pacific,
Cold in Central Asia...

But that's about it for cold.

Enormous warm anomaly over the Arctic from Arctic amplification with significant heat records tumbling in Australia.
Speaking of Australia (again)...

-Hottest November ever.
-Hottest Spring on record and +2 °C above the 1961-1990 average.

First ever spring with an anomaly above +2 °C.

Impressive volcanic eruption on the island of Lembata, Indonesia 🇮🇩 yesterday at 9:45 am local time.

Ash column reached over 55,000 feet (17 km) into the atmosphere. The white cloud at the top is called Pileus.

🎥 by Teguh Dwi Hartono.

You can see the eruption from space.

You can see it for yourself 👇

Pileus clouds?

They are amazing and are an indication of air rising very quickly through the atmosphere.

They are usually indicators of severe weather above a cumulonimbus. But explosive volcanic eruptions do a similar job.

Japan witnessed a massive fireball 1:30 am local time on 29 November 2020.

Oh... and #BirdFlu is trending.

We only have 32 days, 16 hours 9 minutes and 15 seconds until 2021.

Is it just me or are there a lot of these recorded in Japan?

5 years in a row of category 5 hurricanes. This has not happened in recorded history going back to 1851.

#Iota is about to make landfall as a powerful category 5 storm. Nicaragua and Honduras can't take another major hurricane. It was only 2 weeks since category 4 #Eta.
The track of #Eta overlaid projected landfall of #Iota is insane. Two major hurricanes within a fortnight in November. Eta struck Nicaragua on 3 November.

Check out this comparison by @WeatherProf.

Heartbreaking.

Here are some of the beasts from the last 5 years.
